  • Digital ballast
    Patent number: 7307389
    Abstract: A ceiling fan including a lamp ballast in which the drive current frequency is controlled by a voltage-controlled oscillator (VCO) that is capable of precise output frequency control. The VCO frequency is controlled by a microcontroller. The microcontroller may control the VCO frequency in response to various input signals including a triac signal, a manual dimmer control signal, a remote control receiver signal, a light monitor signal, a motion detector signal, or a communication interface signal.
    Type: Grant
    Filed: November 8, 2005
    Date of Patent: December 11, 2007
    Assignee: Lights of America, Inc.
